I was having an argument with my son, who barely tightened the lug nuts on my tires, by hand. Is that dangerous? I have to go on a 1,311 mile trip this week…..

There is a thing called a lug-nut wrench with your jack ... you tighten them with that ... most people i know use this to tighten it until they can't turn it anymore ... then, if you need to, they use their foot and body weight to loosen them when necessary ... but ya, finger tight is definitely too loose ...
I would practice yourself, in case you need to change a tire on your trip ...

It varies by vehicle of course. A VW might be less than a Ford F450. There should be a book in the glove box that will tell you what is recommended for your car. The average for several I've worked on lately in the shop seems to be 75 foot pounds.
I've also towed some in where one loose lug nut has eventually led to losing a tire. tell your son step away from the car, and tighten them up tight with your wrench, then stop by a tire repair place and have them set it where it should be.

You didnt mention whether the car is driveable. If it is I would take it back to the shop and tell them to loosen them However, if you cannot drive the car , try some Liquid Wrench on it . Try tapping the lug nut with a hammer Try to find a pipe 2 or 3 feet long to fit over the lug wrench for much more leverage power.

Each car manufacturer has torque specification for there automobile lug nuts. Most people don't do this but good repair shops use torque sticks. I use a torque wrench and follow the manufactures specifications.
You should be careful not to over tighten and also to use the proper sequence because this will prevent rotor warp.Go to this web site for more information: www.free-auto-repair-advice.blogspot.com

They need to be tightened snug with a lug wrench (also called a 4 way) or impact wrench. That's why there is such a tool because only tightening them by hand will cause them to eventually loosen & come off....very dangerous.

They should be tightened to whatever the specified torque setting is for that particular vehicle. If the vehicle is equipped with alloy wheels the torque should be re-checked again after 100 miles of driving.
Not using a torque wrench is dangerous, let alone what your son is doing.

100 foot pounds of torque. Yeah hand tightened isn't really going to cut it. Unless hes got some really strong hands.

I've heard, tighten the lug as tight as you can with your hand, and then tighten it one more quarter turn with the tool.
